Hurricane season officially begins June 1 in the Gulf of Mexico, but preparation should start in May, before the first named storm enters the Gulf. Houston’s plumbing system is particularly vulnerable during severe storms. Heavy rainfall overwhelms drainage systems, flooding backs up sewer lines, storm surge and high winds damage outdoor fixtures, and power outages affect sump pumps and water heaters.
Here’s what Santhoff Plumbing recommends every Houston homeowner do before hurricane season.
1. Inspect and Clean All Outdoor Drains
Clear all area drains, yard drains, and French drains of leaves, debris, and soil accumulation. A drain that barely handles normal rainfall will overflow completely during a tropical storm. Check that all drain grates are seated properly and that nothing has grown over or into the drain openings.
2. Check Your Sump Pump (If You Have One)
Pour several gallons of water into the sump pit to verify the pump activates and removes water promptly. Check the power connection and discharge line. Consider a battery backup unit — when power goes out (which it will during a major storm), your sump pump is your primary defense against basement flooding.
3. Know Where Your Main Shutoff Is — and Test It
During a flood or hurricane-related plumbing emergency, you may need to shut off your water supply quickly. If you haven’t tested your main shutoff in years, do it now. A stuck or corroded shutoff valve that won’t close when you need it is a serious problem. If your shutoff valve is hard to turn or leaks when operated, have Santhoff replace it before storm season.
4. Inspect Backflow Prevention Devices
Houston’s sewer system can experience backflow during major flooding events, pushing sewage back into homes through floor drains, toilets, and sinks. Backflow prevention devices — including check valves and backwater valves on your sewer line — are your defense against this scenario. Have a plumber inspect these devices before storm season begins.
5. Secure Outdoor Gas Appliances
Before a storm, shut off the gas supply to all outdoor appliances — grills, fire pits, gas lamps — at the individual shutoff valves. If a major storm is approaching, consider shutting off gas at the main meter and have Santhoff restore service after the storm.
6. Protect Your Water Heater
If your water heater is in a garage or lower level of the home, it’s vulnerable to flood damage. Know where the gas shutoff for your water heater is located so you can shut it off quickly if flood water enters the space.
7. Have Santhoff Plumbing on Speed Dial
Post-hurricane plumbing calls in Houston overwhelm most plumbing companies for days and weeks after a major storm. Santhoff Family Club members receive front-of-the-line priority service after emergencies — one of the most valuable benefits of membership during Houston’s storm season.

Frequently Asked Questions
What should I do immediately after a hurricane if I suspect plumbing damage?
Shut off water at the main supply, do not use any plumbing until the system has been inspected, document all damage photographically for insurance, and call a licensed Houston plumber for an assessment.
Can flooding damage my sewer line?
Yes. Flood conditions can force debris, mud, and tree roots into sewer lines, and the saturated soil surrounding lines can cause settling and joint separation. A post-storm sewer camera inspection is wise if you experienced significant flooding.
Does homeowner’s insurance cover hurricane plumbing damage?
Standard homeowner’s insurance typically covers sudden plumbing damage from storms. Flood damage typically requires separate flood insurance through the NFIP or a private carrier. Review your policy with your agent before storm season.
When should I call for emergency plumbing during a storm?
If water is actively entering your home from a broken pipe or backed-up sewer, or if you smell gas, call immediately — (713) 665-4997 for Santhoff Plumbing’s 24/7 emergency line and 911 for any safety emergencies.
